Guest guest Posted March 18, 2011 Report Share Posted March 18, 2011 I've been reading that the greatest quake threat is in the Pacific Northwest. Some estimates are that the fault there is overdue for another quake and they tend to be huge. Also: 1. Measurements show that in some areas where the De Fuco (sp.) plate is being pushed under the North American Plate, the land is moving at 1.5 inches per year. This means that the land has moved up to 15 feet well inland and up to 30 feet near the coast. 2. Near the coast, the land is also buckling. That means as the North American Plate rides up over the other one, there is a fold in the land some distance back from the coast because of the pressures involved. This fold is related to a "compression zone" which is an area in addition to the main fault that could slip when the quake happens. The slip would happen because of the above mention fold in the land and the stress it is under. Once the blockage near the coast is gone, all of that will try to snap slat as well. 3. The last quake in the 1700's sent a large tsunami all the way to Japan where thousands were killed. On the American side, some land subsided many feet and was flooded by the sea. There is no way to know when they next quake will happen up there, but when it does it will probably be a big one. In a message dated 3/17/2011 10:35:03 A.M.

I don't know, but I do believe we have another significant one due in Haiti, and along the North American coast within the ext few years. I am not entirely convinced that we are done seeing activity in Japan either. Administrator Quote Link to comment Share on other sites More sharing options...
